Notes.
Distinguishing characters include the annual ascending habit, dense often
partly exserted panicles with hispid or villous peduncle, axis, branches and
pedicels, acuminate sometimes aristulate usually partly glabrous glumes, short
florets relative to the glumes, long-awned lemmas entirely obscured by hairs,
and beaked biaristulate paleas. Panicles are produced thoughout the plant from
its base on sometimes short, axillary branches. The lemma lacks the submarginal
grooves, which characterise many species in the genus, but may have a
depression at its apex on both sides of the awn. Characters distinguishing E.
armitii from the closely allied E. stipacea are given under the
latter species. E. armitii has been confused with E. squarrosa,
which is a perennial with erect usually coarser habit, a denser indumentum on
the glumes, and lacks axillary panicles.

Endemic. The species
is distributed N of the Tropic of Capricorn; known in W.A. only by P.K.Latz
4010. Recorded habitats include deep or skeletal, clayey, loamy and sandy
soils over quartzite, granite or laterite, which are sometimes saline or
gravelly; also seasonally wet sites near swamps, salt pans, lakes and
watercourses, and disturbed ground. Flowers and fruits Feb.-June (late-summer
to early winter).
